nvethernet: Fix build for Linux v5.14 and v5.17+

Browse Source 
The nvethernet driver fails to build for Linux v5.14 and Linux v5.17+
kernels. In Linux v5.15 the return type of the get/set_coalesce
callbacks were updated. In Linux v5.17 the parameters for the
get/set_ringparam callbacks were updated. In Linux v6.1 the
weight parameter for the netif_napi_add() function was removed and the
function netif_napi_add_weight() was added for passing the weight
parameter. Add the necessary kernel version checks to ensure that the
drivers build with the different versions of the Linux kernel.
